To all whom. it may concern.

Be it known 'that I, lVAi/ricu IIAYDEN, citizen ot the United States. residing at (talveston, in the county of Galveston and State of 'l exas, have inveut il certain new and useful Improvements in Spring-'heels. ot which the following is'a specification.

This invention relates to improvements in wheels ot the class known as spring wheels, or wheels with yieldable tires, and has for one of its objects to improve the. construction and increase the ellicieuey and utility of devices of this character.

;\nother object of the invention is to provide a wheel ot this character in which provision is made For resisting the pressure produced by abnormal weight, and to provide a wheel having independent sets of compound springs adapted to etl'ectually support the load when the vehicle is subjeeted to abnormal weight.

Another object ot the invention is to provide a wheel wherein provision is made lor renewii'ig impaired or broken parts without discarding the remainder of the wheel.

Another object of the invention is to provide a wheel wherein the parts may he the wheel from the vehicle or detaching any of theyieldable portions of the device.

lVith these and other objects in view, the invention consists in certain novel features of construction hereinafter shown and described and then specifically pointed out in the claim; and in the drawings illustrative of the preferred embodiment of the invention, Figure 1 is a side elevation of the improved wheel partly in section; Fig. 2 is an enlarged detail of a portion of the improved wheel illustrating its construction more fully; Fig. 3 is a section on the line 3-3 of Fig. 2;:Fig. {is an enlarged detail view illustrating a ll'lfitlllltfttl'lOIl in the construe: tion; Fig. 5 is a perspective view of one of the leaf springs employed inthe modification shown in Fig. l; Fig. (3 is a sectional detail illustrating another modification in the construction of a portion of the improved wheel; Fig. 7 is a view similar to Fig. illustrating another modification in the construction.

Corresponding and like parts 'are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved. wheel comprises a hub 10,

tain conditions if required.

spokes 11, an inner t'elly 12, an outer telly l3 spaced 'lrom the inner folly, and a tire H bearing around the outer t'etly 13. Formed at suitable intervals in the inner t'ace ot' the outer telly 13 are small sockets or pockets 1?). Seated in each of the sockets to is a coiled spring 18, the inner end of the coil being extended through the outer 'l'elly and riveted or otherwise rigidly secured therein as shown at. 19. At their outer ends the coils 18 bear against the outer l'ace ot' the inner t'elly 12 and are connected thereto by extending the inner terminal through the inner t'elly and riveting or otherwise securing it therein as represented at 20.

Surrounding each of the coiled springs ISis a larger and preferably conical shaped coil spring 2t. the outer terminal of each of the conical coils being extended through the outer fully 12' as shown at 22 and bolted or otherwise secured in position as shown at 23 and the inner ends extended through the inner telly and riveted or otherwise secured therein, as shown at 28.

In Figs. 1. 2 and 3 the springs 18-2l are separate and distinct, and independently secured to the telly members, while in Fig.

7 the two springs are shown integral with the inner ends of each pair of springs bent into a loop 31 which is inserted into apotket 32 formed in the inner telly and secured in position by a pin 33 passing ,through the side walls of the telly and likewise through the socket and through the loop 31. This form of spring may be employed under cer- The two coils are thus retained in their proper relative position, anddo not interfere with each other during the operatitm of the wheel.

Secured to the inside l'aee of the inner telly 12 is a guard member. preferably in the form of two segmental plates 24-25, bolted or otherwis secured, as shown at '26, to the inner folly and lapping over a portion of the outer t'elly. Secured to the outer face of the inner telly are other guard plates, preferably in two parts similar to the plates 2l25, one of these other guard plates be-- ing represented at 27. The two sets of guard plates are preferably united to the inner lelly by the same bolts 26, as shown in Fig. 2. At their confronting ends the plates i2-li25 are provided with registering notches which bear around two of the bolts 26, the heads of the bolts and the notches thus bearing upon both of the plates and assisting in holding the latter in position. The outer portions of the guard plates are free to slide over the outer face of the outer felly 13 when the wheel is in operation, and thus perform the two-fold function of a means for preventing lateral movement be.- tween the felly members and also to cover .the otherwise open space occupied by the 10" invention to any specific material from.

which toconstruct the same.

The improved wheel may be employed wherever yieldable wheels are required, and

is designed to replace the ordinary pneumatic tires of automobiles and similar vehicles.

In Fig. 4 a modification'in the construction is shown which consists in dispensing with one-half of the coiled springs 18-21 and substituting therefor leaf springs represented at 29, each of the springs being bolted or otherwise secured at 33 to the outer felly a d forked at the opposite end for bearing upon the opposite sides of the hold ing portions 20 and 28 of the next spring and in contact with the outer face of the inner felly 12. This slight modification may be found advantageous under certain conditions, and does not constitute a departure from the principle of the invention or sacrifice any of its advantages. Formed in the outer felly 13 at suitable. intervals are inwardly opening sockets 29, and connected to the inner felly 12 in radial alinement with each socket is a pin 30 whichextends toward. the socket and adapted to enter the same when pressure is applied to the wheel by the load, to prevent lateral displacement between the parts under the strain of the load. By this means the etficiency and utility of the wheel is materially increased with out materially increasing the expense or weight. I i I Having thus described my invention, what is claimed as new is: t

A wheel including an inner felly, an outer felly spaced from the inner felly, a plurality of outer springs spaced apart and connected to said fellies, an inner spring within each ofsaid outer springs and connected respectively to said outer and inner fellies, guard plates each formed of segmental members having registering notches in their contiguous ends, and fastening devices engaging in one of said fellies through said notches.

In tcstimon 1 whereof, I alfix my signature in presence 0 two witnesses.
